Audi a5 xenon and led tails retrofit

[ginho1981]

Hi, I'm after someone to do a retrofit on my car, i want to install xenon headlights and rear led tail lights. I do know that the rear ones is simple wiring and coding, but apparently the front ones are a little bit more complicated. Is there anyone in london available to do this on my car? If there is someone please give me prices by pm.

Thanks in advance
